Tx Rx Test items of IEEE (O-QPSK) MS2830A MG3710A Transmit power spectral density (PSD) mask Symbol rate Error vector magnitude (EVM) --- * Transmit center frequency tolerance --- * Transmit power TX-to-RX turnaround time * RX-to-TX turnaround time * Receiver sensitivity Receiver interference rejection --- * Receiver maximum input level of desired signal --- *1: The limit value of the EVM measurement depends on the signal quality of DUT. (Measured example: approximately 20% or less) *2: The limit value of the Frequency Error measurement is approximately 15-ppm. *3: The spectrum analyzer will not be used in this measurement item. *4: The MG3710A can add two different signals and output them from the RFx1 port. The frequency (recommended range: ±60 MHz) and level (CN: ±80 db) can also be set at the screen.
